Which organization focuses on consumer protection and competition law in the UK?

The Office of Fair Trading (OFT) was the primary organization that focused on consumer protection and competition law in the UK prior to its functions being transferred to other agencies such as the Competition and Markets Authority (CMA) in 2014. The OFT's mission was to prevent anti-competitive practices in markets and to ensure that consumers were treated fairly by businesses. This included overseeing various aspects of consumer rights, providing guidance to consumers, and ensuring businesses adhered to free competition principles.

The Financial Conduct Authority (FCA) primarily regulates financial services and firms to ensure that consumer interests are protected within that specific sector. While it does have some consumer protection functions, its focus is largely on the financial markets and institutions rather than general competition law across all sectors.

The Financial Ombudsman Service (FOS) handles disputes between consumers and financial companies but does not focus on competition law or broader consumer protection measures beyond financial services.

Her Majesty's Revenue and Customs (HMRC) is responsible for tax collection and enforcement in the UK, and its role does not include consumer protection or competition law in the business sector.

Thus, the OFT's dedicated role in addressing both competition law and consumer protection makes it the correct choice in the context of the question.
